Documentation Overview

Brasil NFe

Brasil NFe MCP

Servidor MCP fiscal brasileiro - sua IA emite NF-e, NFC-e, NFS-e, CT-e, MDF-e e DC-e.

Site - Documentação MCP - Demo ao vivo - Painel

English - Português


O que é

O Brasil NFe MCP é o primeiro servidor MCP (Model Context Protocol) que expõe a infraestrutura fiscal brasileira inteira como ferramentas, recursos e prompts pra qualquer cliente compatível com MCP - Claude Desktop, Cursor, Windsurf, VS Code Copilot, Zed, Continue.dev, JetBrains, ou sua própria aplicação.

Plugue o servidor no seu cliente MCP e o agente de IA passa a emitir nota fiscal por linguagem natural direto na conversa - "emite uma NFC-e de R$ 89,90 pro CPF tal" - e o documento vai pra SEFAZ. A IA descobre as tools sozinha, monta o payload pelo schema e traduz erros da SEFAZ pra linguagem clara.

REST API ou MCP?

Os dois são produtos de primeira linha da Brasil NFe e expõem a mesma infraestrutura fiscal - mesmo backend SEFAZ, mesmo SLA, mesmo suporte humano. A escolha é pelo tipo de integração, não pela qualidade:

Use a API REST quandoUse o MCP quando
Você tem ERP, sistema de gestão ou app próprio com fluxo de emissão já definidoQuer um assistente IA, copilot ou agente decidindo quando e como emitir
O processamento é em lote, agendado ou movido por evento de fila/webhookO fluxo é conversacional - usuário (ou agente) no loop dirigindo cada passo
A integração é determinística e você tem controle pixel-perfect da UI/UXO cliente quer plugar Claude / Cursor / Copilot do contador direto na operação
Volume alto, paralelismo otimizado, contratos de payload estáveisSessão interativa, exploratória, ad-hoc por linguagem natural

Os dois conversam com o mesmo backend - dá pra ter o ERP integrado via REST e ao mesmo tempo plugar a IA do contador no MCP. Quando uma rota nova entra na API REST, ela já vira tool MCP automaticamente. Roadmap fiscal unificado, dois canais de consumo.

  • brasilnfe://empresa/atual - snapshot da empresa logada
  • brasilnfe://nfe/{chave}/xml - XML autorizado
  • brasilnfe://nfe/{chave}/danfe - DANFE em PDF
  • brasilnfe://evento/{chave}/{seq} - evento por sequencial
  • brasilnfe://recebidas/{periodo} - notas recebidas no período

5 prompts prontos

  • emitir_nfe_simples - fluxo guiado de emissão NF-e
  • cancelar_nota - cancelamento com validação de prazo
  • diagnostico_emissao - checagem completa antes de emitir
  • relatorio_periodo - relatório fiscal do período
  • carta_correcao - fluxo de CC-e com validação de campos permitidos

Quick start

1. Pegue seu token

Crie uma conta gratuita em brasilnfe.com.br e copie o token no painel. Modo homologação é grátis - você emite documentos de teste à vontade sem nada ir pra SEFAZ de produção.

2. Configure seu cliente MCP

Pega o arquivo correto em examples/ e cola na config do seu cliente:

  • Claude Desktop
  • Cursor
  • Windsurf
  • VS Code Copilot
  • Zed
  • cURL puro (JSON-RPC)

Substitua SEU_TOKEN_AQUI pelo token real e reinicie o cliente.

3. Fala com a IA

Code
"Liste o status da SEFAZ pra SP."
"Consulte o CNPJ 39.658.743/0001-99."
"Emite uma NFC-e de R$ 89,90 pro consumidor com CPF 123.456.789-00."
"Cancela a chave 35..., justificativa: erro de digitação no valor."

Pronto. A IA descobre as tools sozinha, pede o que falta, valida, monta o payload, envia pra SEFAZ, e te entrega chave + protocolo + XML + PDF.

Demo sem cadastro

Abra brasilnfe.com.br/ai e converse com o assistente fiscal direto no navegador. Não envia pra SEFAZ de produção, mas mostra o fluxo completo com DANFE renderizado em tempo real ao lado do chat.

Boas práticas

  • Sempre rode em homologação (tipoAmbiente: 2) antes de produção. Documento de teste tem CNPJ permitido e numeração separada - zero risco fiscal.
  • Consulte cliente/produto/tributação antes de criar. As tools *_consultar evitam duplicatas e dão à IA o contexto pra reusar cadastros existentes.
  • Confirme operações destrutivas. Cancelamento e inutilização são irreversíveis - a IA já é instruída a confirmar, mas verifique no seu fluxo.
  • Feche sessões idle. DELETE /services/Mcp libera quota mais cedo.
  • Auditoria sai automática. Todas as chamadas MCP ficam logadas no painel da sua empresa por 5 anos (LGPD-compliant).
